Relevant information about car fog lights is as follows: 1. Introduction: Car fog lights are installed at the front and rear of the vehicle, used for road illumination and safety warnings during driving in rainy or foggy weather. They improve visibility for both the driver and surrounding traffic participants. 2. Purpose: The function of fog lights is to make the vehicle visible to others in conditions of reduced visibility due to fog or rain.

What Level Does SP Grade Engine Oil Belong To?

SP grade is the highest level in the engine oil industry. Characteristics of SP Grade: SP engine oil solves the low-speed pre-ignition issue in turbocharged direct-injection engines, meaning the engine has better low-speed anti-knock performance, resulting in smoother engine operation. It enhances the lubricant's protection against wear on the engine's timing chain. Due to the higher certification standards, SP oil also possesses excellent features such as anti-wear, cleaning, and fuel efficiency. Requirements for SP Standard Engine Oil: It must contain low-SAPS (low sulfur, low phosphorus, low ash) additives, which effectively prevent excessive byproducts from oil combustion from adhering to the particulate filter, thereby reducing the likelihood of clogging.

Are the filling locations for antifreeze and windshield washer fluid the same?

Antifreeze and windshield washer fluid are not filled in the same location. Windshield washer fluid filling port is located in the engine compartment: Open the engine compartment and look for a blue cap (some may be other colors). The cap will have a windshield symbol or a similar water spray symbol. Pour the windshield washer fluid directly into it, and it usually takes about 1.5 liters to fill. Antifreeze should be added by opening the expansion tank cap: The expansion tank is a transparent container marked with minimum and maximum levels. Fill the antifreeze between these two levels. Never open the cap to add antifreeze when the engine is hot, as the cooling system is under high pressure. Opening the cap when hot may cause high-temperature coolant to spray out, leading to dangerous consequences.

What Are the Causes of Increased Car Noise?

Here are the reasons for increased car noise: 1. Engine-related components: The issue is not with the engine itself. This includes damage to the external soundproofing equipment of the engine, such as worn-out soundproofing cotton or aging soundproofing components. It could also be due to a loose screw or a damaged rubber gasket related to the engine. 2. Door-related components: This includes screws inside the door and the sealing strips. Since the door is very close to the cabin, any noise from it can be more noticeable. 3. Tire-related components: Tires are in direct contact with the ground and are prone to generating noise. If the tires are aging or if foreign objects are stuck in the tread gaps, they can also cause noise when rubbing against the ground.
